Explain how mantle plumes (hot spots) provide evidence for the rate and direction of tectonic plate movement
Evaluate how the distribution of earthquakes and volcanoes provides evidence for the current theory of plate
tectonics
Describe a lithospheric plate and identify the major plates of the earth
Describe how earthquakes and volcanoes transfer energy from earth’s interior to the surface
Model the factors that cause tectonic plates to move
Model tectonic plate movement and compare the results of plate movement along convergent, divergent and
transform boundaries
Investigate the possible effects of mudslides, earthquakes, flooding and volcanoes on human-engineered
structures such as dams, homes, bridges and roads
Explain how technological advances lead to increased human knowledge (satellite imaging, deep ocean probes,
seismic sensors, etc.)
Identify and describe natural hazards that occur locally and globally (earthquakes and volcanoes)
Document how scientists use technology to continually improve estimates of when and where natural hazards
occur
